1. Most people could be trained to code. The most important trait in a programmer is persistence. Momentum built from solving past problems is a powerful force.
2. The idea of needing to be atypical in order to be successful is damaging and wrong. What matters is practice.
I understand what you are trying to get at, but there a lot of very smart people outside of the realm of software development. The ideas you are perpetuating raise the barrier to entry.
But to say that half the population bus not capable of programming? That is elitist nonsense. Especially given the breath of the field.
Abstract thinking is really not that easy. Just try to go to a shopping mall and teach people simple math or programming concepts.
I have taught at least a dozen people to code. A good number had no idea what was going on for a while, but left knowing how to handle the basics.
Coding, math, and related subjects are made harder than needed by focusing on the abstract too much. Most of the concepts taught in a typical computer science degree are not difficult once you strip away the terminology.
I'm also not sure how you see these opinions stemming from an elitist filter bubble. I know what I know because of how I've been educated. Anyone who put in the same amount of work (within a reasonable margin) would know the same things.
You appear to have hallucinated a version of what I've said and are arguing against that.
I could be misunderstanding something about what you're saying.
Is that elitist?
